They used to use towers and triangulate using 3 of them to tell pretty much were you were but they couldn't tell your altitude or room from it. The phones with GPS can be used to say what floor you are in. A lot of newer laptops also have built in GPS tracking.
Pretty much anything that transmits a signal that can be IDed can be used to track you or ID you.
Masking the signal is great except one problem suppose you have a good PI on your but and he knows you are the only person in the room and he picks up a new signal coming from that room. Think he will associate it with anyone else.
however, if you went to a crowded Internet cafee and used whatever device you wanted it could be any number of people. He would have to actual hear the conversation not just the signal to ID it as you.
I guess what you really want to do is determine the level of caution you need. It is one thing to dodge a PI working for your wife, verses say company man, or fbi, or cia... Then you got to look at what is at risk is it just money, your livelihood, prison or your actual life.
